Lessons *and there diverges into a pair of laterale each of, which endsin a short vertical riser, 36 which delivers direetly'rto a chamber 37in which a pair of inlet Ivalves 355 is arlranged. The laterals from thefuel passageI 35 are Within a easing 38 which is preferably formedintegral with the cylinder casting, and immediately above this portion38` is a horizontal exhaust channel. :39 which is connected to theseveral exhaust valve chambers 40. ily arranging the fuel supply passagein the manner indicated, the fuel (i. e., the carbureted air) is causedto pass through the water jacket and delivered to Water jacketed inletchambers and. is therefore eontinuously surrounded with the heated waterof the water jacket. The temperature oit this water is always such as toprevent con densation of the gasolene or other hydro carbon but at thesaine time preventsthe carbureted airfrom reachinga temperature ofcombustionbefore it enters a cylinder.

The detachable casing member 14 is provided in its bottom 'with anoil-retaining chamber 4t2, which at its middle is depressed "at 43.Arranged above the, oil chamber l2 are two horizontal shelves 44. Eachof these Shelves is flanked at its ends by vertical ribs or flanges 4:5.and at its middle is provided with a flange i6 which is slightly less inheight than the llanges The two shelves are separated at their adjacentende so as to 'orm a passage l? communicating with the depressed portionorf the main cha1nber l2, and the shelves at their ends do not extend tothe end oitthe casing, thus leaving openings 48, the arrangement beingsuch that oil discharged upon the shelves 44C will be retained thereonat a depth equal to the height of {ianges' 4i?) and will flow over thoseflanges into the reservoir l2-JMB. Each of the shelves la is placedbeneath a pair of cranks of the crank-shaft, each crank dipping downinto the space between flange el@ and one of the flanges 45.

Leading from the lowest point in the de pression lf3 is a straineroutlet 5]. which discharges into pipe leading upwardly to a pump casing33. This pump is substantially 'lt-shaped, the stem of the l beingthreaded into the casing; i4 and bored to ceive reciprocating pump'plunger 5e norn mally urged outwardly by light spring within the casingand at its outer end engagging a cam 5G carried by the cam shazt't :20.The head ot the is pertorated from. end to end and provided with aninlet valve 57 and au outlet valve 5S and leading from the outletpassage beyond 'valve 58 is a pipe 59 which is connected to a pair `ofdivergent delivery pipes 6l, the ends ot' which pass through easing 14so as to discharge upon each shellc Communicating with chamber 42 is avertical supply passage 62 in the upper end of which is rotatablymounted a filling neck or .litting 63, said neck being normally closedby a swinging,T perforated plate 65, the rarrangement being such that'air may have free 'flow into the crank casing through perforations otthe plate but no dirt will enter owingto the `fact that under runningcon# ditions the filling fitting is presented ddwnwardly. ln order totill the casing with) oil, the vfitting G3 is turned upwardly and plateG5 swung to one side so that lubricating oil may pour freely into thecasing until a desired level has been reached,indication ot the levelbeingl secured by opening cock G6.y

Formed in the main casing' member l0 4between the level oit the crankshaft 15 and cam shaft 20 is a horizontally arranged bea-ring 7l, inwhich is mounted an intermediate shaft T2. At its outer end shaft. TQcarries.

a coupling member 73 adapted to detachably eopera'te with a couplingmember 74 carried by the shaft 75 of a magneto or other generator 76mounted upon a projecting bracket "(7 carried vby or formed integralwith casing member 1th Shaft 72 carries a spiral gear 78 which mesheswith a spiral gear 79 on crank shaft l5 and also carries, a spiral gear8l. which mesheswith a spiral gear 82 carried 'by cam shaft 20.," Thetwo spiral gears 78 and 8l are preferably oppositely pitched so that thethrust of' one will counterbalance the thrust of the other. The innerend of aft 72 is supported in a bear ing 83 carried by the adjacentcapbearingi9.
